论文摘要
我们研究了两个量子机械振荡器系统束玩具模型的动力学，这些模型通过将截断为零空间尺寸线性化重力耦合到巨大的标量场和标量QED。标量奖励玩具模型映射到相阻尼的振荡器上，而标量QED玩具模型大约映射到经受两光子阻尼的振荡器系统上。玩具模型为解决与完整标量QED和弱重力场系统相关的开放系统量子动态提供了潜在有用的见解，特别是针对初始标量场系统叠加状态的逆转勘探的操作探针。
We investigate the dynamics of two quantum mechanical oscillator system-bath toy models obtained by truncating to zero spatial dimensions linearized gravity coupled to a massive scalar field and scalar QED. The scalar-gravity toy model maps onto the phase damped oscillator, while the scalar QED toy model approximately maps onto an oscillator system subject to two-photon damping. The toy models provide potentially useful insights into solving for open system quantum dynamics relevant to the full scalar QED and weak gravitational field systems, in particular operational probes of the decoherence for initial scalar field system superposition states.
